Gebrauch :
ChIP Wash Buffer can be used for Chromatin Immuno-
precipitation assays using the protocol provided below.

NOTE: ChIP protocols vary widely. The following protocol
should be suitable for most experiments.

•Wash cells twice with PBS at room temperature, resuspending to approximately 5x105 cells/ml (approximately 2x107 cells total). Add formaldehyde to a final concentration of 1% and incubate at room temperature for 10 minutes.

•Terminate cross-linking reactions by adding glycine to a final concentration of 0.125 M.

•Pellet cells (2,000 RPM, 5 minutes) and wash once with ice cold PBS.

•Resuspend cells in 6 ml Lysis Buffer (sc-45000) by mixing gently.

•Collect crude nuclear extract by microcentrifugation at 2,000rpm, 5 minutes.

•Wash again with PBS. Pellet may be frozen or processing may be continued as follows:

•Resuspend pellet in ~1.9 ml Lysis Buffer High Salt (sc-45001) and transfer to 2 ml microcentrifuge tube for the sonication step.

•Sonication conditions should be optimized since results may vary using different sonifiers. The following conditions were established by using a Sonics VC130 with a 3 mm tip probe.

•Sonicate on ice at power output setting = 5–6, continuous mode, 4 times at 30 second intervals.

•Centrifuge extract for 15 minutes, 10,000 rpm at 4° C and save super-natant (chromatin).

•Determine protein concentration of supernatant.
•For the IP step we recommend using 100-500 μg protein and 0.1–1 μl TransCruz reagent (0.2–2 μg).

NOTE: Investigators may wish to consider using the primary antibody conjugated to sepharose or magnetic beads as an alternative to using secondary immunoprecipitation reagents (e.g., Protein A-Agarose) as described here. Combining primary antibodies directed to different epitopes of the same protein may be advantageous in some cases.

•Preclear the chromatin solution by adding 50 μl Protein A/G PLUS-Agarose (sc-2003) and incubate for 30 minutes at 4° C. Centrifuge at full speed for 5 minutes at 4° C.

•Add primary antibody to the supernatant and incubate overnight at 4° C.

•Add 50 μl Protein A/G PLUS-Agarose (sc-2003) and incubate for 2 hrs at 4° C.

•Harvest beads by centrifugations at 12,000 rpm for 20 seconds and place tube in ice.

•Wash beads twice with 1 ml Lysis Buffer High Salt (sc-45001).

•Wash pellet four times with Wash Buffer (sc-45002).

•Resuspend beads in 400 μl Elution Buffer (sc-45003).

•Reverse cross-links by incubating tube in a 67° C water bath, mixing occasionally over two hours. Remove beads by centrifugation and continue incubating supernatant at 67° C overnight.

•Centrifuge for 3 minutes at 10,000 to remove any residual beads and save supernatant.

•To isolate DNA, extract supernatant once with 500 μl
phenol/chloroform/isoamyl alcohol (25:24:1), vortex thoroughly and separate phases by centrifuging tube for 3 minutes at 14,000 rpm.

•Save the aqueous phase, back extract the organic phase once with 100 μl 10 mM Tris, 1 mM EDTA, pH 8.1 (TE) and pool aqueous phases.

•Extract pooled aqueous phase with 600 μl chloroform/isoamyl alcohol.

•DNA may be concentrated by using commercially available kits.
